Connect your DNS records at OVH to Microsoft 365

Add a TXT record for domain ownership verification

Before you can use your domain with Microsoft 365, you need to prove you own the domain. Your ability to sign in to your account at your domain registrar and create the DNS record proves to Microsoft that you own the domain. This process involves creating a TXT record at your domain registrar with a specific value that Microsoft can look for. When Microsoft finds the record with the correct value, your domain is verified. The TXT record is used only to verify that you own your domain. It doesn't affect anything else and can be deleted once domain verification is complete.

To add the TXT record for domain verification at OVH, follow these steps:

1. Get the TXT value specific for your domain from the Microsoft 365 admin center. For help on finding the value of your TXT record in the Microsoft 365 admin center, see Gather the information you need to create DNS records.

2. If you're not already signed in to the OVH DNS Zone page for your domain, follow the steps in Sign in to OVH to manage your domain's DNS records to get there.

3. In the DNS Zone page, select the Add an entry tile.

   

4. In the Extended records section of the Step 1 of 3 - Add an entry to the DNS zone pane, select TXT.

   

5. In the Step 2 of 3 - Add an entry to the DNS zone pane, enter the values from the following table:

   Record Type	Subdomain	TTL	Value
   TXT	leave blank	3600 (seconds)	MS=msXXXXXXXX

   • In the Value field, replace MS=msXXXXXXXX with the TXT value you gathered earlier from the Microsoft 365 admin center. The value shown in the table is only an example.

6. Select Next.

7. In the Step 3 of 3 - Add an entry to the DNS zone pane, select Confirm.

   

8. Wait a few minutes before you continue, so that the record you created can update across the Internet.

Now that you added the TXT record at your domain registrar's site, go back to the Microsoft 365 admin center and complete the domain ownership verification process. When Microsoft 365 finds the correct TXT record, your domain is verified.

To verify the record in the Microsoft 365 admin center, follow these steps:

1. Sign in to the Microsoft 365 admin center.

2. From the left navigation bar, select ... Show all, and then select Settings to expand it.

3. Under Settings, select Domains.

4. In the Domains page, select the ellipsis ⋮ next to the domain that you're verifying, and then select Start setup.

   

5. In the Verify you own your domain page, make sure Add a TXT record to the domain's DNS records is selected, and then select Continue.

6. On the Add a record to verify domain ownership page, select Verify.

7. After you verify domain ownership, the How do you want to connect your domain? page appears. The rest of the wizard walks you through adding additional DNS records to connect your domain to Microsoft 365 services.
